What values should OTG_HCFG & OTG_HFIR (and USBPHYC_TUNE for internal HS PHY on STM32F7x3xx) be set to for Isochronous data?As I understand it Isochronous data should be allocated 1 to 3 'slots' per Start of Frame (SOF) in full speed mode and up to 1...

I'm working on extending the capabilities of the STM32CubeMX Library to support higher data rate isochronous IN data (e.g. UAC audio). Currently I have host code that requests and receives isochronous data every 1ms frame (not every micro-frame).Is t...

Posted on June 07, 2018 at 17:51I'm using an STM32F723 with a customised USB driver to capture Isochronous data.I can capture the data in 4KiB chunks. The data is DMA'd into internal SRAM then modified and copied to internal SRAM then DMA'd to an SD...
